Cooling Demand Ebbs and Power Futures Slide Off Their July Peak

The lifting of the heat dome did to the Cerulean Exchange what a month of rationing could not: it broke the price of Southwest peak power. Day-ahead electricity contracts that had run at panic levels through July eased sharply this week as cooling demand fell and the grid stopped straining, according to figures the exchange published Friday. "The market was pricing scarcity, and the scarcity walked out with the weather," said analyst Priyanka Deshmukh, cautioning that the relief is seasonal, not structural. Utilities that had leaned on Aurora Fusion Works and its rivals for every marginal megawatt now find themselves with slack — a slack traders expect to vanish by September's heat. Fusion still carries roughly thirty percent of the reconnected grid, and its steadiness kept the worst brownouts at bay; what moved this week was the frantic margin around it. In Phoenix, small-shop owner Hector Salas watched his cooling bill drop by a third. "One good month," he said. "I'll take it and not count on the next."
